The effect of a sacrificial layer residue on a cantilever beam in the nano-electro-mechanical nonvolatile memory is investigated for the optimization of reliability characteristics. Different from previous research, pull in voltage model of nano-electro-mechanical nonvolatile memory used triangular residue layer which is considered by real wet etching process. Modified pull in voltage model was...

a molecular imprinted polymer (mip) was computationally designed and synthesized for the selective extraction of metaproterenol (mtp), from human plasma. in this regards semi empirical mp3 and mechanical quantum (dft) calculations were used to find a suitable functional monomers. on the basis of computational and experimental results, acrylic acid (aa) and dmso:meoh (90:10 %v/v) were found to b...

The conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. A novel nano-Au/poly (4-aminobenzoicacid) (PABA) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. The PABA film and nano-Au/PABA film were characterized by scanning...

metallic copper nanoparticles modified glassy carbon electrode is fabricated by reduction of cuso4 in the presence of cetyltrimethylammonium bromide (ctab) through potentiostatic method. as-prepared nanoparticles are characterized by scanning electron microscopy and electrochemical methods. copper oxide modified glassy carbon electrode (nano-cuo/mgce) is prepared using consecutive potential sca...

To closely analyze the dislocation structure evolution during nano-indentation, a multi-scale discrete dislocation plasticity code is modified to include nano-indentation loading. This code couples two length scales, discrete dislocation dynamics and continuum finite element analysis and has been successfully applied to analyze various problems in mechanics and materials science. Description of...

the free vibration of the lattice cylindrical composite shell reinforced with carbon nano-tubes (cnts) was studied in this study. the theoretical formulations are based on the first-order shear deformation theory (fsdt) and then by enforcing the galerkin method, natural frequencies are obtained. in order to estimate the material properties of the reinforced polymer with nano-tubes, the modified...

Manipulating an incorporated scaffold to direct cell behaviors play a key role in tissue engineering. In this study, we developed novel nano-topographic oxidized silicon nanosponges capable of being modified with various chemicals of a few nm in thickness to gain further insight into the fundamental biology of cell-environment interactions in vitro. A wet etching technique was applied to fabric...
